Looks like ASUS has rolled out the ICS update earlier than it's scheduled, as it's being reported the company has set the update available via software update menu via your Transformer Prime device, and then download the Ice Cream Sandwich from there.

Asus made this move probably to appease the Transformer Prime users who were feeling discontent at CES, for a newer better spec-ed Prime TF700T with its 1080p. So to keep their customers happy, this Taiwan-based company announced this wonderful schedule changing on NVIDIA's press conference at CES last night.
